Some clis require flags/arguments strictly follow certain commands or subcommands - i.e. a flag may work in one position but fail (or have another meaning) in another.
e.g. this failed (at time of writing)
$ docker-compose up mysql -f docker-compose-development.yml -f docker-compose.yml up
whereas this works
# Difference: -f flag immediately after main binary name, `docker-compose`
# instead of nested deeper into the command.
$ docker-compose -f docker-compose-development.yml -f docker-compose.yml up mysql
Basically the -f flags for config files must be after the docker-compose
command and not the arguments (up mysql, in this case).
